Non-Invasive Electrical Brain Stimulation for Modulating Human Motor Neuron Activity

Begin with rubber electrodes connected to the electrode cables and insert them into sponge bags.

Soak the bags with an isotonic sodium chloride solution to ensure uniform conductivity at the skin interface.

Insert the electrode-holding bags into non-conductive covers to prevent solution leakage.

Locate the pre-marked spot on the scalp of a human participant, clean, and dry it.

Position the anode, or positive electrode, over the marked area that contains the motor neurons responsible for muscle movement.

Place the cathode, or negative electrode, above the eyebrow on the opposite side of the head. This completes the electrical circuit.

Secure the electrodes to maintain stable contact.

Secure the cables and connect them to a non-invasive electrical brain stimulation device.

Initiate the stimulation. The current excites the motor neurons.

Excited neurons transmit signals through motor networks, enhancing motor neuron activity and reflecting the effects of targeted electrical stimulation.

Connect cables to rubber electrodes, and place the electrodes inside the sponge bags. Ensure that the electrode size and sponge bag size match. Soak sponge bags on both sides with isotonic sodium chloride soluti
